10 Claims.

The present invention relates to a yarn, and particularly to adecorative silk yarn, and process for making the same.

An object of the present invention is to provide an improved yarn givinga variated structure and/or color effect which may be convenientlywoven, knitted or otherwise processed to give yarns, fabrics and othertextile materials of unusual designs.

Other objects will appear during the course of the followingspecification.

In accomplishing the above objects it has been found satisfactory toform a yarn of strands which are preferably intermingled and twistedtogether, the preferred yarn being formed of spun silk and includingstrands of different colors and structure.

In making up the strands to be twisted and/or spun together to form thenovel yam of the 20 present application, it has been found desirable touse the residue from the dressing operation,

which residue is termed long noil.

This long noil is washed and dyed and then is carded by a specialoperation which will not 25 be described.

In carding the noils, the fiber treating elements of the cardingmachines are arranged in such a way that most of the fibers will bealigned, but a substantial number of the fibers of the noils 30 will becoiled and not aligned together with the other fibers.

These curled and unstraightened fibers may be conveniently put in thisposition by special treating operations or in any other desired manner,so long as there is produced in the bands from the carding machine aseries of fibers which are not aligned with the other fibers.

It is an important feature of the present invention that the blending ofthe colors does not take place during the carding operation, inasmuch asa more or less uniform color effect would be obtained, quite differentfrom the variegated effect which it is desired to obtain.

After this carding operation has been performed in the manner described,the material is then subjected to several drawing operations, in whichoperations the group fibers are put through a rubbing procedure, duringwhich rubbing procedure the fibers are brought together 50 in closerelationship with each other and conglomerated.

During this operation several colors are blended together if desired,and long-fibered dressed silk maybe introduced at this point. The amountof colors blended together and position of the color is preferablyaccording to a predetermined design, which it is desired to produce.

After this step the fibers are submitted to a roving process and thenfinally to a spinning process. 5

The spun silk so produced is of special construction and gives theappearance of a multi colored thread of mottled appearance, with a largenumber of tufts sticking out of the sides of the thread at desirablyspaced intervals.

The accompanying drawing shows the appearance of one type or specimen ofthe yarn prepared and a cloth which may be prepared therefrom.

The above and other objects will appear more clearly from the followingdetailed description when taken in connection with the accompanyingdrawing which illustrates a preferred embodiment of the inventive idea.

In the drawing:

Figure 1 shows one specimen of the yarn upon a relatively small scale.

Figure 2 shows a portion of Fig. 1 upon a much enlarged scale, and

Figure 3 shows the fabric made from the yarn of Figs. 1 and 2.

In the drawing, the body of the yarn is designated by the numeral l0 andthe tufts are designated by the numeral II. The maximum twist of theyarn is at the non-tufted portions I0 where a plurality of strands maybe twisted together fairly tightly and closely. At the tufted portionsII the non-straightened fibers abovedescribed are held together by thetwisted together lengths of fibers constituting the body I0.

During the spinning the twist is taken up, for the most part, by theportions ID of the yarn.

A particular feature of the present invention is the fact that nofillers, oil or other materials are used to hold the fibers together.

What is claimed is:

1. A spun silk yarn having a multi-colored mottled appearance consistingof strands of colored long-fiber dressed silk, and a strand of coloredpartly carded silk noils, said strands being twisted together and theuncarded part presenting tufts sticking out at spaced intervals. I

2. The method of making a novel spun silk yarn consisting in carding.silk noils until a silk noil strand is provided presenting tuft portionsand interlocked substantially straight fibers, blending long-fiberdressed silk with said strand of silk noils, and finally spinning saidsilk noil strand and said long-fiber dressed silk until a finished yarnis provided with the uncarded part of the silk noils projecting as tuftsat spaced intervals.

3. A novel spun yarn consisting of a partly carded noil strand andlong-fiber strand twisted together with the long-fiber strand and partof the noil strand forming the body of the yarn and the uncarded part ofthe noil strand forming projecting tufts at spaced intervals.

4. The method of making a novel spun silk yarn consisting in partlycarding silk noils to form a silk noil strand having tufts formed fromthe uncarded portion of the noils and interlocked substantially straightfibers, blending long-fiber dressed silk with the silk noil strand bysubjecting the silk noil strand and the long-fiber dressed silk at thesame time to several drawing operations, subjecting the blended silknoil strand and long-fiber dressed silk to a roving machine, and finallyspinning the roved material.

5. A spun yarn formed of a plurality of fiber strands, at least one ofsaid strands being a sliver of noils, the product of a carding machinewherein the noils are carded suificiently to have part of the fibersthereof substantially straight and part forming tufts and at least oneother of said strands being formed of long-fibers, said tufts projectingat spaced intervals along the yarn.

6. A non-filled novel spun silk yarn consisting of a plurality ofstrands of colored long-fiber dressed silk, and a strand of silk noilstwisted together to form a single yarn, some of the fibers of said noilstrand being uncarded and out of alignment so that they will project astuits along the length of the finished yarn.

'7. A composite yarn composed of a plurality of difierent coloredstrands arranged in close relationship so that the final yarn will havea multicolored mottled appearance having a large number of tuftssticking out at spaced intervals, at

least one of said strands being composed of partly uncarded silk noils,said uncarded silk noils forming said tufts.

8. A composite nib or nub yarn composed of a plurality of diiferentcolored strands including a silk noil strand which have been subjectedto several drawing operations together in making the final yarn, thenoils of said noil strand being partly uncarded whereby a multi-coloredyarn is presented having a number of tufts of the noil strand stickingout at spaced intervals, said uncarded silk noils forming said tufts.

9. An article of the character described composed of colored long-fiberdressedsilk, and a strand of colored silk noils, the silk noil strandand the long-fiber dressed silk being in close relationship for theirfull length, the noils of said noil strand being partly uncarded and theuncarded part projecting at spaced intervals in the
